Randomized Controlled Trial Comparative Study Clinical Trial
Subtenons lidocaine injection for postoperative pain relief after strabismus surgery in children: A prospective randomized controlled trial.
We previously reported a pilot study of the use of subtenons lidocaine after primary, unilateral strabismus surgery in children. This study suggested an association between subtenons lidocaine administration at the conclusion of surgery and a reduction of pain in the immediate postoperative period. As a result of this pilot study we performed a full-scale prospective, randomized controlled trial to fully evaluate the efficacy of this intervention. ⋯ This study showed that an intraoperative injection of subtenons lidocaine is associated with a significant reduction in postoperative pain during the first postoperative hour for all types of childhood strabismus surgery. There was no difference between the groups in the need for systemic analgesia.

ReviewEffect of postoperative pain treatment on outcome-current status and future strategies.
The effect of postoperative pain relief on morbidity and hospital stay is reviewed. ⋯ The effects of pain relief on outcome remains debatable, despite beneficial effects of pathophysiological responses. Future outcome studies are required where optimised dynamic pain relief is integrated with a multimodal rehabilitation programme.

Incisional pain is a common form of acute pain. Previously, the authors studied persistent pain behaviors caused by incisions, using animal models for postoperative pain. In this study, the authors measured tissue pH and hind paw temperature before and after incision to understand factors that may activate and sensitize nociceptors in the incision. ⋯ A decrease in pH occurs immediately after incision and is sustained for at least 4 days. During the period of decreased tissue pH, pain behaviors are evident. When the tissue pH returns to normal, pain behaviors are diminished. The decreased pH is localized at the incision site and not to areas surrounding the incision. Decreased pH likely contributes to nociceptor sensitization and pain related behaviors after incision. The magnitude of the pH change varies among tissues. An increase in hind paw skin temperature does not play a role in these pain-related behaviors.

Can chronic poststernotomy pain after cardiac valve replacement be reduced using thoracic epidural analgesia?
The aim of our study was to evaluate the use of thoracic epidural analgesia (TEA) in acute pain management after cardiac valve replacement and determine if the incidence of chronic pain related to the sternotomy was reduced by the use of TEA. This patient group was chosen to exclude pain related to the use of the internal mammary artery and angina pectoris. ⋯ We found in our small material that TEA provided excellent analgesia in the peri- and postoperative period, but we did not find a protective effect of TEA on chronic poststernotomy pain, neither weak pain nor severe pain.
